Gallery: Comparing painter's tape

The timing was perfect: 3M sent samples of its Scotch Blue painter's tape and I had a whole basement worth of trim that needed painting, so why not try out a bunch of different tapes to find out how they compare?
The results were not what I expected. While all the tapes performed well in a control test on a freshly painted piece of drywall, when I applied them to my basement walls and painted the trim next to them, none was perfect, and almost all pulled paint off the wall. Here's how they rated, from best to worst. All prices are for 24-millimetre by 55-metre rolls.

Scotch Blue
Claims: For pros and do-it-yourselfers. Clean removal with no surface damage and super-sharp paint lines.
Performance: Easy to handle and apply, but curls when pulling a long strip off the roll, making it easier to stick to itself. Left clean lines but also pulled off several patches of wall paint, both fresh and several months old. Also tears during removal. Big disappointment.
